CARL A. WINGREN, OF BEMIDJI, MINNESOTA.

GUN-SIGHT.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed January 5, 1910. Serial No. 536,474.

To all whom it may concern:

Be it known that I, CARL A. l/VINGREN, a citizen of the United States,residing at Bemidj i, in the county of Beltrami and State of Minnesota,have invented certain new and useful Improvements in Gun- Sights, ofwhich the following is a specification.

My invention relates to improvements in gun sights designed particularlyfor rifles, and consists of improved means for securing the sight to thebarrel in connection with improved means permitting of more accurate andeasier adjustment than with the ordinary sight.

To this end my invention consists in the features of construction andcombination hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a side elevation of a rifle fitted with my improved sight; Fig. 2is a perspective view of a portion of the gun barrel showing the rearsight; Fig. 3 is a similar view of a portion of the gun barrel showingthe front sight; Fig. 4 is a section on line ae-m of Fig. 3; Fig. 5 is asection on line hh of Fig. 2; Fig. 6 is a section on line yy of Fig. 2;Fig. 7 is a section on line 'w w of Fig. 2; Fig. 8 is a section on line0-4) of Fig. 2; Fig. 9 is a section on line z-z of Fig. 3; Fig. 10 is aperspective view of a support forming part of the invention adapted tobe arranged in connection with a polygonal barrel; Fig. 11 is a similarView of a support shown arranged in connection with a round barrel; Fig.12 is a perspective view of a portion of the rear sight; and Fig. 13 isa side elevation of a portion of the gun barrel and rear sight.

Referring to the drawings A represents a gun and B the barrel thereof.

In constructing the front sight according to my invention, I provide thebase plate C having angular shaped side walls 2, fitted under similarlyshaped side Walls 3 of a groove 4:, cut transversely through the top ofthe barrel.

The sight block D is made of any desired design and has similarly shapedside walls 5, fitted to a groove 6 extending transversely through thesupporting plate C.

Where the sight is used in connection with a polygonal shaped barrel, itis formed with downwardly extended flanges 7 to fit over the upper sidefaces of the barrel, and where used in connection with a round barrel iscurved to conform to the barrel. The sight is locked within the supportblock by a screw 8 extending through the block and into the supportingbase, and as will be evident, this will also look the supporting base inits groove, since the engagement of the sight with the top of the barrelprevents sliding of the sight and base transversely of the barrel.

The rear sight consists of a plate E secured by means of a screw 9 tothe base 10, corresponding with the base C, and similarly fitted in atransverse groove through the top of the barrel. The plate E has anupwardly flanged rear end 11 formed with the sight notch 12. A springstrip 13 rests upon the plate and is supported at its front end by thescrew 9 and has an upwardly flanged rear end 14 fitted against theforward face of the flange 11. The spring 13 has a sight l5corresponding to the sight notch 12 and is formed in its rear face witha distance scale 16. The spring strip is so constructed as to normallyspring upward at its free end and to be adjusted by means of a sleeve 17slidably inclosing said spring and having slidallole engagement 18 withthe sides of the p ate.

In operation, the spring strip being adjusted by means of the sleeve tobring the desired distance mark at the top of the flange 11 adjusts therear sight to the proper position for the use of the sight notch 15 inconnection with the sight C.

My improved means for supporting the sight upon the barrel which it willbe noted is the same in both the front and rear sights, firmly locks thesights against movement either longitudinally or transversely of thebarrel through the simple expedient of the screw connection between thesight block and the supporting portion of the sights.

I claim as my invention:

1. The combination with a gun barrel, sight means therefor, a baseremovably supported upon the gun barrel, a sight member secured at oneend to said base and having its other end free and normally projgctingawgay from the barrel, and an adjusting to the top of said barrelagainst lateral moveplate being fitted to said barrel to 'revent 15ment, said plate having one end upturned, a lateral movement a stripsecured at one end strip secured to one end of said base and to saldplate and having its other end uphaving its other end upwardly turnedalongturned adjacent to the upturned end of said 5 side the upturned endof said plate, the upi plate, and mean fi ra d 1 eup tu ed turned end ofsaid strip being formed with end of sa d strip towar and r a scale andmeans for adjusting the upturned magnum end of said strip toward andfrom said In testimony whereof I aflix my signature barrel. in presenceof two witnesses. 10 3.
